Will office plants survive congés annuels ?

4 plant leaves sitting in plastic dixie cups filled with water are showing signs of depression and listlessness. They struggle to survive during the annual holiday of their office owner, growing roots out of the same water as last week. The plants' owner left the leaves behind in "la clim" (akin to death for these tropical plants) with two unattentive office mates, who clearly ignore any of plants' needs. Save the leaves!
